Silver Alert in Pennsylvania: How MEPAS Works and Who It Covers

Pennsylvania does not operate a program called Silver Alert. If an older adult with dementia or another cognitively impaired person has gone missing in the Commonwealth, call 911 and ask the responding agency to request activation of the Missing Endangered Person Advisory System, known as MEPAS. The Pennsylvania State Police run MEPAS as the statewide equivalent, and it covers the same situations a Silver Alert would in other states, plus more.¹

Do not wait. The 24- or 48-hour waiting period you may have heard about is a myth in Pennsylvania, and with a vulnerable person every hour matters.

Who MEPAS Covers

Under 35 Pa.C.S. § 7025.1, MEPAS applies to any missing person believed to be at “special risk of harm or injury,” without a minimum age or a required diagnosis.¹ That is a meaningful difference from Silver Alert programs in other states, which often limit eligibility to adults over 60 or 65 with a documented cognitive impairment. In Pennsylvania, the usual qualifying situations are:

A senior with Alzheimer’s disease, dementia, or a similar condition who cannot safely find their way home.
An adult with a developmental or intellectual disability who cannot reliably seek help on their own.
A person of any age with an acute medical need — missed dialysis, insulin, oxygen, or other time-sensitive treatment.

Law enforcement is asking whether the person’s absence poses an immediate safety concern, not whether the family can produce paperwork proving a diagnosis. If you believe your loved one is in danger, say so plainly when you call.

What to Have Ready When You Call 911

Roughly six in ten people living with dementia will wander at least once, and the chance of serious injury rises with every passing hour. Pulling together the following details before officers arrive, or while you are still on the phone with the dispatcher, keeps the search moving:

A current photograph. Clear and recent matters more than flattering.
Physical description: height, weight, hair, eyes, scars, tattoos, how they walk.
Exactly what they were wearing when last seen, including shoes.
Medical conditions, medications, and whether a missed dose creates urgency. A physician’s letter confirming a cognitive impairment strengthens the case for activation.
Vehicle details if they may be driving — make, model, color, year, license plate.
Places tied to their past: former homes, workplaces, churches, favorite routes. People with dementia often head toward locations from earlier in life.
Whether they have wandered before, and where they were found.

How the Activation Works

Your local police or sheriff’s department opens the case. After a short investigation to confirm the person is genuinely missing and that the situation suggests risk, the local agency contacts the Pennsylvania State Police to request MEPAS activation.² The PSP reviews the information and, if the case meets the threshold, authorizes the advisory and pushes it into distribution channels.

The statute also allows local agencies to notify the public and ask for community help independently, so your local department may post on social media or alert local news before the formal MEPAS advisory goes out.² That parallel work is normal and welcome.

How the Public Hears About It

Once MEPAS is authorized, the information moves through several channels at once. The Emergency Alert System reaches local radio and television. PennDOT can light up electronic highway signs with vehicle descriptions and plate numbers. Local media outlets and police social media accounts share the details online.

One expectation worth adjusting: the loud Wireless Emergency Alerts that arrive on cell phones are governed by the FCC under 47 CFR Part 10 and delivered through FEMA’s Integrated Public Alert and Warning System.³ AMBER Alerts for abducted children routinely trigger these phone alerts; missing endangered person advisories do not always do so. Whether a WEA goes out depends on the circumstances and the alert category the issuing authority selects. Highway signs, broadcast media, and social media may be the primary way neighbors see the alert.

If Your Loved One May Have Crossed State Lines

Separate from the public advisory, law enforcement enters the missing person into the FBI’s National Crime Information Center database. For someone with a cognitive or physical impairment, the record goes in under the “Disability” category, which covers anyone “missing and under proven physical/mental disability or is senile, thereby subjecting themselves or others to personal and immediate danger.” That entry includes 24/7 contact information for the handling agency so any officer in the country who encounters the person can verify the record and coordinate a safe return.⁴

MEPAS itself only pushes notifications within Pennsylvania. The NCIC record is what extends the safety net nationwide, so a traffic stop in Ohio or a welfare check in New Jersey can surface the information immediately.

If You Spot Someone Matching an Alert

Call 911 right away. Do not try to physically stop or detain the person. Someone with dementia may not understand what you are doing and can react with fear or aggression. Keep a safe distance, keep them in sight if you can, and give the dispatcher your exact location.

Useful things to report: the direction the person is heading, whether on foot or in a vehicle, what they are wearing, and whether anyone is with them. On a highway, note the lane, direction, and the next exit before you call.

Prevention Steps for Caregivers

The best outcome is never needing MEPAS at all. A few practical measures reduce the odds of a wandering incident:

Secure exits with deadbolts that take a key from both sides, childproof knob covers, or door-chime alarms. Bedroom door sensors help with nighttime wandering.
Consider a GPS device designed for people with dementia — watches, clip-on trackers, and shoe inserts are all available. None is perfectly accurate, but any of them narrows the search area dramatically.
Keep identification on the person. A medical ID bracelet engraved with name, condition, and an emergency contact number tells anyone who encounters them what is happening. Sewn-in clothing labels do similar work.
Build a “wander kit” ahead of time: a current photo, physical description, medical details, and a short list of places the person might head for. Having it ready shaves minutes off the first call.
Tell your neighbors. A neighbor who recognizes your loved one and calls you directly can resolve things before 911 is ever needed.

Phone location-sharing can supplement a dedicated GPS device and ping you when the person leaves a defined area. Tracking is one layer in a safety plan, not a substitute for supervision.

Where MEPAS Fits Among Other Alerts

AMBER Alerts are reserved for children under 18 who have been abducted and are believed to be in danger. MEPAS covers everyone else at risk — seniors with dementia, adults with disabilities, people with urgent medical needs — whether or not an abduction is suspected.¹

At the federal level, the Ashanti Alert Act of 2018 created a notification network for missing adults 18 and older who fall outside both AMBER and Silver Alert frameworks, often cases involving suspected abduction of adults who are not cognitively impaired.⁵ For a missing loved one with dementia or similar impairment in Pennsylvania, MEPAS is the right system to ask for.
